Today, communication system and information technology are developed at full speeding, and mobile communication develops faster. There are many kinds of mobile communication systems, and FH-CDMA mobile communication is one kind of them. It is mainly makes analysis and descriptions of the structures of FH-CDMA communication system and system principle and so on. It mainly introduces the basic principle of FH-CDMA system, and explains the methods of the realization of sending circuits and FH-CDMA synchronization synthetically.It finally introduces the FH-CDMA network schemes and applications in GPS-AVL. |
